I'd like to apologise if this question is stupid or if it was asked ten thousand times - I haven't found an answer to it. Quite possibly due to mediocre English or abominable knowledge of physics.
So, let's say that we're able to convert 100% of energy that falls on photovoltaic cell to electricity. This means that NO energy is lost. Now assume that all countries on the planet use these cells. Won't it increase temperature on the Earth? Not that I'm really concerned about it, my guess is that even if we'd cover million square kilometers of Earth with them this change won't be very big (if it would happen), but maybe I'm wrong? Would Earth temperature rise? If yes, why? If not, why? How much?
